Given, Width (W) = 40 meters when Perimeter (P) = 210 meters.

*The chain link enclosed all sides of the field.
Find, Length (L) = ?

We know for a Rectangle, P%5BR%5D=2L%2B2W
Substituting,
210=2L%2B2%2840%29
210=2L%2B80
2L=210-80=130
cross%282%29L%2Fcross%282%29=cross%28130%2965%2Fcross%282%29
L = 65 meters, Answer

Check,
P=2L%2B2W
210=2%2865%29%2B2%2840%29
210=130%2B80
210m=210m

Thank you,
